Another thing I didn’t know existed. If your hot water tank is a distance from your shower or faucet where you have to wait for hot water, this device might be for you.
You install the pump on the hot water line near your hot water heater. At each faucet where you want instant hot water, you install a simple bypass valve unit. The pump recirculates hot water through the bypass to heat the water in the line.
You set a timer so it isn’t recirculating water at night and other times you don’t need instant hot water.
